TOP 5100 – The Versatile LSR Dosing System

The allrounder for versatile use

TOP 5100 – The Versatile LSR Dosing System for the Most Demanding Applications

The ELMET TOP 5100 is a powerful and versatile dispensing system for the precise processing of liquid silicone rubber (LSR). As a true all-rounder, it combines high performance, maximum flexibility and cost-effectiveness – the ideal solution for users who need more than a basic model but do not require the full range of features offered by a high-end system.

With high process stability, precise dosing, and a wide range of applications, the TOP 5100 is particularly well-suited for the industrial mass production of LSR molded parts. High-resolution volumetric meters ensure an exact mixing ratio of the silicone components and guarantee reproducible results in the injection molding process.

Thanks to its extensive standard features and numerous expansion options, the TOP 5100 can be flexibly adapted to a variety of production requirements. Whether for standard applications or demanding LSR projects, the TOP 5100 offers the optimal balance between functionality, process reliability, and investment costs.
